I must say, I hate the patagonian worker's front, and would like to talk politely with someone who likes it to see their point.
Like, the impression I have by playing with them is that they are basically a "internationale occupation zone" in south america, almost as a protectorate, a colony if you will, led by national collaborators but still kept together by foreign aid.
This usually would be a problem but not enought for me to really finds a faction to be terrible as I consider them, but they are also imposing a draconian level of conscription maybe only similar to Long Yun in TNO mod, they are totalitarian, but not ideologically totalitarian, but because they exercise total control over the population there, there are conscription squads that basically moves into villages, take all men, women, old people and children and employ them to fight on the coming war with the north, I would say they are going even further than the nazis did with the volkssturm since the nazis didn't conscripted women (I have nothing against women fighting, my point on his argument is that they are forcing more people to fight than the nazis did).
You also can see how the locals hate this as a event allows you to install political comissars, and if you don't you get another event about people deserting.
The result of such draconian and totalitarian measures is that the war to unify argentina ends being terribly deadly, comparable to the balkan wars, the AI get easily over 200 thousand people dead for such a stretch of Land.
